This question is inspired by the second crash of the Boeing 737 MAX. I am focusing on the second crash because after the investigation of the first was completed it was clear that there was a danger situation, but it is not clear whether Boeing managers fully disclosed the extent of the problem. Would the planes have been grounded earlier if they did so?
As far a I know the US authorities investigated and prosecuted the manipulation of the certification process, not the events related to the second crash.
Now, in a globalised economy it may happen often that the actions committed in one country have an impact in another country. So, I would like to know: if someone is acting in a country, but by negligence causes the death of one or more persons in another country. Which country should prosecute the actions?
